Application filed March 10. 1902. Serial No. 97,416,

. To all tch/om it may concern/.-

fered with by the surface of the air flue, and

to permit proper drainage of the sections, while at the same time not interfering with the circulation of the air through the flue.

Another object is to provide a design of section readily formed of cast metal, the flue therein being made by coring, and contained entirelyl within a single radiator section, rather than formed by the relative disposition of ribs or flanges of two adjacent loops, as is common in the prior art.

Other objects of my invention are the provision of a radiator section with an air flue therein of serpentine form, gradually enlarging asit rises in the section, so as to retard the flow of hot air, and discharging laterally into the room.

The above objects, as well as other advantages hereinafter to appear, I attain by means of the construction illustrated in preferred form in the accompanying drawings, in which- Figure 1 is a vertical central section through a radiator section embodying my improvement, and Figure 2 is a front side elevation thereof;

Figures 3 and 4 are respectively transverse serzionson thelines (3) and (4) of Figure 1, an

Figures 5 and 6 are respectively a transverse section and a horizontal section showing a modified form of my improved device.

Referring more particularly to Figure 1, it will be seen that in carrying out my improvements I have formed a cast radiator section or loop`7, within which there is a clear, open air passage 8 extending upward through the section, and opening laterali at the point marked 9, so that the air wil be discharged outward into the room and away from the walls. The air passage 8 in the preferred` form of the construction shown in Figures 1 to 4 inclusive, begins at the bottom of the loop at one side, so as not to interfere with the connection 10 or opening through which the loop is connected with the next adjacent loop, nor with the proper direct arrangement of the two openings on opposite sides, as indicated by the dotted lines 10a4 and lOlO in Figures 2 and 4. The air passage 8 is made of increasing capacity toward the top, so that as the air becomes heated and expands it may be retarded in flow and have freer movement, which will facilitate its heating and circulation, the iiue is also made to follow a serpentine course, as shown, so that the air will be the better heated and retarded and mixed in passing through.

It is to be observed in connection with my invention that the loop or radiator section has the air passage entirely inclosed within the same, this being produced by coring the passage, the core being supported on proper chaplets, as is usual in foundry practice of this kind, and the inlet and outlet are yat the extreme bottom of the casting.

In the modification shown in Fi ures 5 and 6 the air passage, at the lower en is forked, as indicated at 8a and 8b, the two forks straddling the connecting opening l0; but there is no place for water to collect, and the passages between sections are straight-away and unobstructed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A radiator section comprising a single casting having an inlet, and an outlet at the extreme bottom for complete drainage of water, a steam'space and an integral air tube extending through said space opening through the bottom of the radiator and formed on a reverse curve, said tube enlarging toward the top and having a free opening through the side of the radiator, whereby the heated air is retarded in its flow as it expands and is discharged in a lateral direction.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
